Your Simple Ingredient Checklist
This recipe uses a handful of simple ingredients to create a truly spectacular result.
The Ingredient Lineup:
- 2 lbs of Yukon Gold potatoes, peeled and chopped
- 1 whole head of garlic
- 4 tbsp of unsalted butter
- ½ cup of heavy cream, warmed
- Salt and freshly ground black pepper to taste
- A drizzle of olive oil (for roasting the garlic)
Step-by-Step Instructions
The secret to this easy recipe is roasting the garlic while the potatoes boil.
Part 1: Roast the Garlic
- Preheat Oven: Preheat your oven to 400°F (200°C).
- Prep the Garlic: Slice about ¼ inch off the very top of the head of garlic to expose the tops of the cloves.
- Roast: Place the garlic head on a small piece of aluminum foil. Drizzle the exposed cloves with a little olive oil. Wrap the garlic loosely in the foil and place it in the preheated oven to roast for 30-40 minutes. The garlic is done when the cloves are very soft, fragrant, and lightly golden.
Part 2: Cook the Potatoes and Mash
- Boil the Potatoes: While the garlic is roasting, place your peeled and chopped potatoes in a large pot. Cover them with cold, salted water. Bring the water to a boil and cook for 15-20 minutes, or until the potatoes are very tender and can be easily pierced with a fork.
- Drain and Mash: Drain the cooked potatoes well and return them to the hot, empty pot. Let them sit for a minute to allow any excess moisture to evaporate. Begin to mash the potatoes with a potato masher.
- Add the Roasted Garlic: Once the garlic is done roasting and cool enough to handle, simply squeeze the softened, caramelized cloves out of their skins and directly into the pot with the potatoes.
- Make them Creamy: Add the butter and the warmed heavy cream to the pot. Continue to mash everything together until the potatoes are smooth and creamy.
- Season and Serve: Season generously with salt and pepper to your taste. Serve immediately while hot.

Frequently Asked Questions (FAQ)
1. What are the best potatoes to use for mashed potatoes? For the creamiest, most buttery mashed potatoes, Yukon Gold potatoes are the absolute best choice. They have a naturally waxy, creamy texture and a rich, buttery flavor. Russet potatoes are another good option as they are very starchy and will create a light and fluffy mash.
2. Can I make these mashed potatoes ahead of time? Yes, this is a great make-ahead side dish for the holidays. You can prepare the mashed potatoes completely, then place them in a slow cooker on the “warm” setting for up to 2-3 hours before serving. You can also store them in an airtight container in the refrigerator for up to 3 days.
3. How do I reheat leftover mashed potatoes? To reheat, you can place the mashed potatoes in a microwave-safe dish and heat in the microwave, stirring occasionally. For a better texture, you can also reheat them in a saucepan on the stovetop over low heat. It’s a good idea to stir in a splash of milk or cream to bring back their creamy consistency.
4. What can I add to these mashed potatoes for extra flavor? This recipe is a fantastic base. For extra richness, you could stir in 4 ounces of softened cream cheese or a ½ cup of sour cream along with the butter and heavy cream. A sprinkle of fresh chopped chives or a handful of extra shredded Parmesan cheese would also be delicious additions.
